以热泵为中心的综合社区能源系统（HPICES）展示了利用低品位热能废物满足空间供暖和制冷等能源需求的前景。热泵废水热回收（HP-WHR）方案是HPICES的一种方法，该方案提出通过级联热泵系统从社区废水中回收低品位热能。本文详细介绍了HP-WHR系统的概念，评估了该系统的潜在性能和经济性，并探讨了其应用潜力。经济分析表明，由于目前天然气的能源成本较低，HP-WHR系统的初始成本较高，基于使用固定能源价格的生命周期比较，HP-WHR系统的成本高于传统的住宅和轻型商用HVAC系统- WHR系统。针对特定应用的部件选择和系统设计优化，再加上不断上涨的燃料价格，将使HPICE在不久的将来与传统系统在经济上具有竞争力。引文:研讨会，ASHRAE交易，第86卷，第一部分，加利福尼亚州洛杉矶

Heat Pump Centered Integrated Community Energy Systems (HPICES) show the promise of utilizing low-grade thermal energy wastes for energy requirements such as space heating and cooling. The Heat Pump-Wastewater Heat Recovery (HP-WHR) scheme is one approach to an HPICES that proposes to reclaim low-grade thermal energy from a community's wastewater effluent through a cascaded heat pump system. This paper details the concept of an HP-WHR system, evaluates the potential performance and economics of such a system, and examines its potential for application. Economic analysis shows HP-WHR systems to be more costly on the basis of life cycle comparison using constant energy prices than conventional residential and light commercial HVAC systems due to the present low energy costs for natural gas and high initial costs of the HP-WHR system. Component selection and optimization of system design for specific applications coupled with rising fuel prices should make HPICES economically competitive with conventional systems in the near future.
